When performing interpolation movement on W-axis ,
The “OFFS”, ”LENG” Parameters must be set as the LABEL attached on the Robot.
The value described on the LABEL is valid in case of No.1 posture of ORIGIN.
If you want to select other posture of origin by using the INDICATOR of the machine, set
"OFFS" again.
( Refer to "Parameter/PARAMETER(0)/4.OFFS” in Chapter 5 of User's Manual)
There are Two Ways of interpolation movements on W-axis when there is TOOL OFFSET.
(Refer to "PARAMETER(0)/1.BODY/6.TOOL" ).
W Axis Fix (Robot Command “FIX 1”) W Axis Rotation (Robot Command “FIX 0”)
( See FIX Command )
Be careful of the operation of point teaching when there is TOOL OFFSET.
W Axis Fix: Teaching while keeping TOOL direction fixed (Refer to next page)
W Axis Rotation : Teach after accurately setting the TOOL OFFSET.
Select TOOL and teach point in order to work with the W-axis fixed if it is possible.
Especially, in case of the W-axis rotation, there maybe occur some occasions that the
mechanical part of robot stays only at unreachable point and be unable to follow the
commands of controller during the successive interpolation movement of the AMOVs
making arc.
